Picking a pet identification tag for your Tosa is like purchasing an insurance policy – you do so with the devout wish that you’re never going to use it. The “possible cost” of not having a pet ID tag is more costly than the “real cost” of buying the pet tag itself.
The type of pet identification tag that you buy is vital, so take 5 minutes or so to consider it. Whimsically purchasing a collar tag just because it’s cheap or trendy often ends up being a regret, long-term.
